UNITED STATES PATENT OFFICE.

THEODORE W. PHINNEY, OF CHICAGO, ILLINOIS.

IMPROVEMENT IN COMBINED CURB-STONE AND GUTTER FOR STREETS.

Specification forming part of Letters Patent No. 206,130, dated July 16,1578; application filed April 13, 1878.

To all whom it may concern:

Be it known that I, THEODORE W. PHIN- NEY, of Chicago, in the county of(look and State of Illinois, have invented a new and useful Improvementin Combined Curb-Stone and Gutter for Streets, of which the following isa specification:

Figure 1 represents a perspective view of a portion thereof; Fig. 2, avertical sectional view taken at the line or m, Fig. 1; and Fig. 3, atransverse sectional view taken at the line y 3/;

The object of my invention is to make a cheap, durable, and substantialcurb-stone and gutter for streets, that can be readily laid, and at thesame time be neat in appearance, sufficiently tight to carry water, anddurable.

The invention consists in making a curbstone and gutter combined, moldedfrom concrete in separate sections, which are then hardened, so as toform finished pieces for sale and use whenever required.

In the accompanying drawings, A represents one piece or section of mycombined curbstone and gutter as it is taken from the mold in which itis formed. The edges are provided with a tongue, B, and groove (3, orother equivalent close-fitting joint, which will admit of the piecesbeing laid, as shown in Fig. 1, making a smooth and continuouscurb-stone and gutter.

By molding my combined gutter and curbstone from a concrete made largelyof Portland cement, or other material that will harden after it ismolded, so as to make a curb-stone and gutter nearly or quite assubstantial as stone, I am able to make the two combined, and of therequired shape and construction to be adapted to the street for thepurpose desired without any cutting or expensive labor. I also providesaid curb-stone with the hole or opening D, through which the hi tching-strap may be tied, to do away with the necessity of hitching-rings andother devices which are now used.

Fig. 3 represents the position in which the curb-stone and gutter isplaced when in use, the driveway of the street being filled against theedge E of the gutter.

I contemplate varying the thickness and height of the curbstone portion,as well as the width and thickness of the gutter portion, of myimprovement, and it will be observed that I may use any of the otherwell-known close-fitting joints that can be readily molded fromconcrete, insteadof the ton gue-and groove joint shown in myapplication.

Having described my invention, what I claim, and desire to secure byLetters Patent, is

As a new article of manufacture, a combined curb-stone and gutter, A,molded in sections from concrete, which are then dried or hardened toform a finished article, like tiling, ready for laying, and are providedwith closefitting joints, substantially as described.

THEODORE W. PHINNEY.
